description: Wire rippy into Codex CLI as a PreToolUse hook.
---
rippy supports [Codex CLI](https://github.com/openai/codex) via
`--mode codex`. The hook setup follows the same pattern as the other tools:
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{ "type": "command", "command": "rippy --mode codex" }
]
}
]
}
}
```
Configuration files, safety rules, and handlers are shared across every
mode — see [Configuration overview](/configuration/overview/) to write
rules once and have them apply everywhere.
